4 Claims.

This invention relates to telephone booths and its object is to simplifyand improve the construction of such booths.

A feature of the invention is the provision of a 5: plurality ofindependent securing means whereby the walls of the booth are held inassembled relation at their lower ends without the use of a base.

Another feature is the provision of a novel 16" guiding mechanism forthe booth door which efiected simultaneously and in timed relation withsimplifies the construction of the booth while permitting a freermovement of the door.

Another feature is the provision of a lighting fixture and means wherebythe use of separate housings for the switching device and the lampsocket is avoided.-

Another feature is the provision of means whereby the operation of thelamp and the fan is 2'0 respect to'the movement of the booth door.

Another feature is the provision of a ventilating system whereby theventilation of the booth is efiected in an efficient manner and whereinthe noise generated by the operation of the fan is 25 reduced to aminimum level.

Other novel features of the invention and advantages will appear fromthe following description'an'dby the claims appended thereto, referenoebeing had to the accompanying drawings in which? i Fig. 1 is a frontelevation view of the booth shown in perspective and 'with portions ofone of the side walls cut away; Fig. 2 is atop view showing the roof andlouver plates with portions cut away;

Fig. 3- is a cross-sectional view of the top portion of the booth takenon line 3-3 of Fig. 2';

Fig. 4' is a cross-sectionalview taken on line I 44 of Fig. 2;

socket and the switch taken on line 9-9 of Fig. 8;

jFig. 10 is a top view of the combined lamp socket and. switch unitshowing the casing with portions cut away and the switch in its operatedposition;

Fig. 11 is a cross-sectional view of the switch and lamp unit taken online ll--H of Fig. 10;

Fig. 12 is a side view of the switch and lamp unit showing theconnecting rod and lamp socket with portions cut away; and

Fig.'13 is an enlarged view of a springused for mounting the fan on itssupporting frame.

As shown in the drawings the telephone booth of this invention consistsof walls Wl, W2, W3 and W4 which are held in angular relation at theirlower frontend by two angle-shaped metallic members 28 and El and attheir lower rear end by triangularly shaped metallic members 22 and 23secured to the booth walls by a plurality of ordinary wood screws 24,shown in Fig. 1, members and 2! being'in turn welded perpendicularly orformed integrally with a cross-brace 25 which serves to maintain theportions PI and P2 of front wallWl in space relation atthis point.

The walls WI, W2, W3 and W4 are held in angular relation at their upperends by a ceiling 26 resting on the top ends-off wall's W2' and W4 asshown in Figs; 2 and 3 'and is secured thereto by a number of woodscrews 21. On the top ends of walls W2 and W4 above the ceiling 26 ismounted a roof 23 provided with two oppositely disposed openings 29 and30 which are fitted with louver plates 3! and 32, the roof being heldsecurely by a number of wood screws 21' A vertically disposed partition33 extends from ceiling 26 to roof 28 to form two compartments 0 and CIfor housing a fan assembly unit FA consisting of an ordinary'motor M anda fan wheel FW and a lighting fixture LF including a controlling switchCS, shown in Figs. 2 and 3.

The front wall WI is provided with an opening OP fitted with a doorformed of two folding sections FI and F2. The folding section Fl ispivoted to one side of wall WI by a number of hinges, such as H3, shownin Figs. 3 and 4. The pin of the top hinge H3, however, is secured tothe movable hinge flap'48 by screws 41 and rotates therewith upon thefolding movement of the door. This hinge pin is formed integrally with arod portion 45 extending above the ceiling 26 in a bearing in the formof bracket 55 for mounting a lever member 44, this bracket being securedto the front wall of the booth by screws 56 and 51.

The lighting fixture LF consists of plates 34 and 35 held to the ceiling26 by a number of clamps, such as 36 and 31 shown in Fig. 3, and thelower disposed plate 34 is provided with a plurality of angularlydisposed air openings dl shown in Fig. 1 and its central portion isfitted with a translucent dome-shaped glass shade 38. On the top surfaceof ceiling 26 is securely mounted a bracket 39 fitted with a casing 40having a cover 40' provided for housing the terminals of the lamp socket4i and a controlling switch US which may be of any well-knownconstruction having an operating arm such as 43 for connection with thearm 44 at the end of rod 45, such connection being effected by alengthwise adjustable bar 49 extending through an opening in the wall ofcasing as shown in Figs. 2, 3, 11 and 12.

The ceiling 26 is provided at its rear right corner with a squareopening fitted with a similarly shaped frame 6| held securely thereon bya num-v ber of screws 62. This frame is provided at its corner portionswith inwardly extending lugs such as 63 and 64 provided for hookingsimilar ends of a plurality of spring members, such as 65, the otherends of these members being disposed tangentially and hooked tocorresponding lugs 66 and 61 carried by the motor housing 68, on thearmature shaft of which is mounted the fan wheel FW for rotation in theopening 60 of ceiling 26. r

The door section F2 is provided at its upper portion with a bracket 10held securely thereon by a number of screws 12 and on the pivot of thisbracket is mounted a slider member H which cooperates with a guideformed by two parallelly disposed rails 13 and M for controlling themovement of the door from its folded position as shown in Fig. 1 to itsunfolded position as shown in Figs. 2, 3, 4 and 6. The rails 14 and 13are secured to the front Wall of the booth by the sets of screws 16 andH engaging spacer members 18 and 19 at each end of the rails, theceiling being provided along the rails with an open slot 80 shown inFigs. 2, 3, 4, 5 and 6 connecting the interior of the booth to thecompartment Cl at the top of the booth in order to assist in the exhaustof the air from the booth as will be hereinafter described in detail.

The motor M of the fan is connected to the current supply line 8|through the controlling switch CS, the cable 82 and the wires 8 and 85,and a manually operable switch 86 shown in Fig. 1 is provided adjacentthe telephone apparatus TA in the booth for independently and manuallycontrolling the operation of the fan, the telephone apparatus beingpreferably positioned directly in the current of air generated by thefan.

In the use of the booth of this invention upon a predetermined movementof the booth door from its folded open position shown in Fig. 1 to itsunfolded closed position shown in Figs. 2, 3 and 4 as controlled by themovement of slider ll between the guiding rails 13 and I4 is effectiveto impart movement to the switch arm 43 through its connection with thebar 49 for causing the operation of the lamp 42 and simultaneously theoperation of the motor fan M.

The operation of fan wheel FW is effective to generate a current of airpassing through an air inlet path including the louver plate 3|, theopenings in the frame FA and the fan wheel opening 60 in the ceiling 26,the air current being directed in the interior of the booth toward thegeneral location of the telephone apparatus.

The air is exhausted from the interior of the booth partly through theopenings in'the lighting fixture plates 34 and 35 and partly through theslot 80 in the ceiling 26 from which it is finally exhausted through thelouver plate 32 separated to the greatest distance to that of louverplate 3! as to prevent any amount of exhausted air to reenter the booththrough this latter path, while the incoming air is prevented frommixing with the exhaust air in the space between the ceiling 26 and theroof 28 by the partition 33.

In this booth the disposition of the air inlet and exhaust paths at thetop of the booth provides an efficient ventilating system and the use ofsprings 65 tangentially connected to the motor M effectively neutralizesthe vibrations generated by the operation of the motor and therebyreduces the noise in the booth to a minimum level, while the lamp andswitch unit together with the use of angle shaped members for securingthe walls of the booth at their lower ends improves the construction ofthe booth and effects considerable saving in cost.

Obviously, minor changes may be made in this invention without departingfrom the scope of the appended claims.

What is claimed is:

1. A telephone booth having a rear wall, side walls, a front wallprovided with a door of folding sections, characterized in this that oneof,
